High- and low-voltage vacuum contactors

This AC vacuum contactor is suitable for power network systems operating at 50–60 Hz, with rated voltages ranging from 0.4 kV to 35 kV and rated currents from 160 A to 2,000 A. It is designed for remote switching on and off, as well as frequent starting and control of AC motors, transformers, capacitor banks, and similar equipment. Its primary applications include variable-frequency drives, soft starters, reactive power compensation, neutral-point grounding resistors, solid-state transformers, and other related devices.

High-voltage vacuum circuit breaker

The ZW32‑12 outdoor high‑voltage AC vacuum circuit breaker (hereinafter referred to as the "circuit breaker") is an outdoor high‑voltage switching device rated for three‑phase AC, 50 Hz, with a rated voltage of 12 kV. It can be equipped with various controllers to form an intelligent vacuum circuit breaker. This circuit breaker is primarily used in urban and rural distribution networks, substations, and industrial and mining enterprises as a switch for making and breaking load currents, overload currents, and short‑circuit currents. The series of vacuum circuit breakers can be paired with corresponding smart terminal controllers to implement reclosing or intelligent remote terminal functions, thereby meeting the requirements of distribution automation applications.

High-voltage isolating switch

Outdoor high-voltage disconnect switches are available in 40.5 kV, 72.5 kV, 110 kV, and 220 kV series, and are suitable for three-phase AC outdoor power systems in power plants, substations, and large industrial and mining enterprises. They are used to switch high-voltage lines under no-load conditions and to electrically isolate and connect/disconnect high-voltage busbars, circuit breakers, and other electrical equipment from energized high-voltage lines during maintenance. These switches feature safety and reliability as well as easy operation. They have passed type‑test reports and IEC export test reports.
